Heart surgery

When I tell people we have an electric gate to our drive it sounds terribly posh. The reality is an amalgam of wrought iron, big blobs of weld and rust attached to ancient aluminium armatures and driven by two electric motors. One half of the gates opens inwards and the other opens outwards - don't ask me why, we inherited this contraption. I dare not park anywhere near these gates and I also tell anyone visiting to avoid parking by them, as they are operated by dialling a phone number. My biggest fear is that someone will dial a wrong number one day and that number will belong to our gate. Not wishing to spend out on a new gate for the drive I am about to attempt to rub down and wire brush the rust, hoping there is gate under rust, and apply several coats of Hammerite. This could take some time.
